What sage people to oracle fusion migration cost actually looks like across the four vendor paths. Build vs buy vs Big-4 vs Oracle Consulting. With offsetting Salesforce licence retirement savings worked through.
Cash-out costs are the easy half. Salesforce licence retirement is the offsetting half. Most quotes show one and ignore the other.
A typical sage people to oracle fusion migration cost conversation gets stuck on the cash-out figure: £280–500k for a 2,000–5,000 employee mid-market customer using Syntra ETL, £600k–£1.5M for the same scope quoted by a Big-4 consultancy as a custom build, £150–300k of hidden internal engineering cost for the 'we'll do it ourselves in Python' route. The number that matters for the actual business case, though, is the net: cash out minus Salesforce licence retirement savings minus Sage subscription savings minus cloud-archive savings.
For a 5,000-employee UK firm running Sage People with full UK payroll integration: Syntra ETL all-in lands £280–500k. Sage People subscription that gets retired (Salesforce Platform licence component) saves £1.3–2.5M/year. Sage People cloud archive (replacing read-only Sage People licences) saves another £60–150k/year on top. The cash-out migration cost amortises against those savings in 3–6 months — before counting Fusion's AI value, workforce analytics, vendor consolidation, or audit cycle reduction.
The vendor decision matrix below frames the full picture. For most mid-market Sage People customers (2,000–10,000 employees, UK or EMEA-centric, standard customization debt), the Syntra ETL path wins on cost, timeline, and risk. For very large global rollouts where the Big-4 wraps the data migration into a broader transformation, the calculus shifts. Use the matrix to figure out which conversation your situation actually sits in.
Six paths customers seriously evaluate. Each with its own cost shape, timeline, and risk profile. Pick the path that matches your situation.
£280–500k all-in cash. 10–14 week timeline. Lowest risk (productised pipeline, multiple prior migrations). Best fit for 2,000–10,000 employee mid-market Sage People customers.
£600k–£1.5M cash. 8–12 month timeline. Higher risk (every Sage People to Fusion build is bespoke). Best fit when wrapped into a broader 30+ country transformation programme.
£0 cash + £150–300k internal engineering. 6–9 month timeline. Highest risk (no productised reconciliation, no audit evidence, no delta replay). Rarely the right answer.
£800k–£1.5M cash. 8–12 month timeline. Source-side Salesforce extraction typically subcontracted. Best fit when also implementing other Oracle Cloud modules in parallel.
£400–700k cash. 6–10 month timeline. Strong on source side, often weak on Fusion HDL semantics. Risk concentrates in the HDL emission and reconciliation phases.
£0 cash this year but £1.3–2.5M/year ongoing Sage People subscription cost. Negative ROI compounds year on year. Rarely a strategic choice — usually a delay tactic.
Phase-by-phase cost loading for a typical 2,000–5,000 employee mid-market migration. £280–500k all-in distributed across six phases.
£20–50k. Customization inventory via Salesforce Metadata API. Custom-field usage report. UK payroll integration architecture diagram. Sized project plan signed off.
£50–100k. Standard crosswalks applied; custom-field mappings configured. UK payroll integration spec extracted. Sharing-rule translation drafted. Cutover calendar drafted against HMRC dates.
£60–125k. Bulk API extracts of all in-scope custom objects. Parquet stage files written with row hashes. Source row counts captured. Reconciled against live Sage People.
£50–100k. Crosswalks applied. HDL bundles generated and locally validated against Fusion 26x schema. Custom-field mappings tested. Error reports generated and triaged.
£60–125k. HDL bundles submitted to Fusion test environment. Reconciliation matrices generated. Sharing rules validated against sample users. Sign-off pack prepared.
£50–100k. 1–2 pay cycle parallel run. Cutover executed in safe HMRC window. 4–8 week Sage People read-only runout. Audit evidence pack finalised. Decommissioning planned.
Every cash-out cost line has an offsetting savings line. For most customers, the net is strongly positive inside 12 months.
£1.3–2.5M/year saved for a 5,000-employee customer (£30–60/user/month Salesforce Platform licence component). Recovers the migration cost in 3–6 months.
£60–150k/year saved by holding history in cloud archive vs keeping Sage People alive read-only. Compounds across the full retention horizon.
Sage People customers typically have 4–8 AppExchange apps (advanced reporting, integration tools, document generation) that retire alongside. £20–80k/year additional savings.
Most Sage People customers run 1–2 dedicated Salesforce admins for HR. Post-migration, that headcount can re-deploy. £80–180k/year freed up.
Workforce analytics, talent matching, payroll anomaly detection — Fusion's embedded AI typically generates £150–500k/year of measurable HR productivity value (separate from cost reduction).
Big-4 audit time on HR data drops 30–50% with Fusion's reconciled, audit-grade data model. £40–120k/year saved in audit fees and internal evidence-gathering time.
A sage people to oracle fusion migration cost analysis covers four cost lines: (1) the Syntra ETL platform subscription for the duration of the project plus a runout period (typically 12–18 months, £40–120k depending on scope); (2) implementation services for crosswalk customisation, UK payroll integration spec extraction, sharing-rule translation, and cutover orchestration (£60–200k for a typical mid-market migration); (3) Oracle Fusion HCM licensing and any new HCM Cloud subscription costs (per-employee per-month, typically £8–18 PEPM); (4) optional consulting wrap for change management, manager training, and post-cutover support (£40–150k). On the offset side: Sage People subscription savings (the Salesforce Platform licence retired or reduced) typically run £30–60 per user per month for the user count freed, which compounds quickly across a 2,000+ employee customer.
Sage people to oracle fusion migration cost via Syntra ETL typically lands at £150k–£400k for a 2,000–5,000 employee mid-market migration (HCM only, with UK payroll integration mapping). The same scope quoted by a Big-4 consultancy as a custom build runs £600k–£1.5M and 8–12 months. Custom Python + Apex scripts cost less in licensed software (£0) but consume 6–9 months of senior internal engineering at fully-loaded ~£800–1,200/day, which works out to £150–300k in hidden cost plus opportunity cost of those engineers not delivering other work. The Syntra ETL path optimises the cash-out cost AND the timeline because the platform is pre-built — you're buying the work that's already been done across multiple Sage People to Fusion migrations.
For a UK-headquartered 5,000-employee firm running Sage People with full UK payroll integration (Sage 50 or third-party RTI), 5+ years of history, and standard Apex/Flow customization debt: Syntra ETL platform + implementation typically lands £200–350k all-in. Add £80–150k for change management and training wrap if delivered by Syntra rather than in-house. Total: £280–500k for a 10–14 week cutover. The same project quoted as a custom Big-4 build typically lands £1M–£2M over 10–14 months. Net: roughly 50–65% cost reduction with Syntra ETL plus a 3–4× faster timeline, which has its own compounding business value (faster Salesforce licence retirement, faster Fusion AI benefit realisation, faster vendor consolidation savings).
Typical phase breakdown for the Syntra ETL approach: Assessment & discovery (weeks 1–2): 5–10% of total cost. Crosswalk design + UK payroll integration extraction (weeks 2–4): 15–20%. Extract & stage (weeks 3–6): 20–25%. Transform & HDL emit (weeks 5–8): 15–20%. Load & reconcile (weeks 7–11): 20–25%. Parallel run + cutover + runout (weeks 11–14+): 15–20%. The cost loading is heavier in the extract / transform / load middle phases because that's where most of the per-customer customisation work sits; discovery and cutover are tighter because the methodology is well-rehearsed. Customers who try to compress assessment and discovery to save 10% of cost typically blow 30–40% of cost in re-work during the middle phases.
The decision matrix every CFO asks for. Build vs buy axis: build (custom code) is £150–300k internal effort + 6–9 months; buy (Syntra ETL platform) is £200–400k cash + 10–14 weeks. Big-4 axis: Big-4 consultancy is £600k–£1.5M + 8–12 months. Niche specialist axis: small Salesforce-to-HCM specialists exist but typically lack Fusion HDL depth — costs £400–700k + 6–10 months. Oracle Consulting axis: capable but typically subcontracts source-side Salesforce extraction — £800k–£1.5M + 8–12 months. The Syntra ETL path wins on the cash + timeline + risk dimensions for the typical 2,000–10,000 employee mid-market Sage People customer. The Big-4 path can make sense for very large global rollouts (10,000+ employees, 30+ countries) where the consultancy's bench depth across non-HCM workstreams provides separate value.
No — the migration cost is the one-time project to get from Sage People to Fusion HCM. The ongoing Oracle Fusion HCM Cloud subscription is separate and typically runs £8–18 per employee per month depending on the modules subscribed (Core HCM, Compensation, Talent Management, Absence Management, Payroll). For a 5,000-employee firm, that's £40–90k/month or £480k–£1.1M/year of ongoing Fusion subscription. On the offset side: the Sage People subscription that's being replaced runs £30–60 per user per month for the Salesforce Platform licence component, so a 5,000-employee retirement saves £150–300k/month or £1.8M–£3.6M/year — typically a net subscription saving of £1.3M–£2.5M/year that funds the migration project and ongoing Fusion subscription combined.
For a typical 5,000-employee customer, the cash-out sage people to oracle fusion migration cost of £280–500k (Syntra ETL path) amortises against the £1.3–2.5M/year net subscription saving in roughly 3–6 months of post-cutover operation. Add the Sage People cloud archive (replacing read-only Sage People licences indefinitely) and the saving compounds further — typically another £60–150k/year saved versus keeping a read-only Sage People org alive. Total: the migration project typically pays back from licence-cost savings alone inside year one, before counting Fusion's AI capabilities (workforce analytics, talent matching, payroll anomaly detection) which generate their own measurable value above and beyond the cost reduction.
Three categories of cost that customers often miss in initial sage people to oracle fusion migration cost analysis: (1) internal time — HR business analysts, payroll managers, Salesforce administrators on your side dedicating 40–60% of time for the project duration, which is ~£100–250k of fully-loaded internal cost not in any vendor quote; (2) Fusion implementation services beyond the data migration — enterprise structure setup, security configuration, payroll calc rules, OTBI / BI Publisher report rebuild — typically £80–200k separately from the data migration; (3) change management beyond technical training — manager coaching, employee comms, post-cutover support desk staffing — £40–100k. Syntra ETL surfaces all three categories explicitly in the project shape conversation rather than letting them appear as 'surprise costs' in month four.
